Excavations conducted on site B were completed in 1969 and revealed five phases of construction:
- The postholes of a circular timber hut about 12 feet (c.3.7m) in diameter, represented the first building on
- In the Flavian period a rectangular stone building of 10 rooms arranged east-west, with a further room attached to
each end to form short south-facing wings. This was augmented during the early-2nd century by a corridor along the
east, north and western sides.
- The house was reconstructed and enlarged in the mid-2nd century at which time it measured about 47 x 137 feet (14.3
x 41.8 m). This building had a channelled-hypocaust fitted in the early-3rd century.
- Most of the building was demolished in the mid-3rd century leaving only 5 rooms standing at the west end, which
continued in use until the end of the 3rd century.
- A small timber shed was erected on the site around 350AD and remained in use until about 430.
